The 4 support legs and the seat are connected by an X-shaped structure with thick metal screws to be sturdier and can withstand higher weights up to 150kg. The smooth and burr-free surface is treated with premium paint to make it super safe and easy to clean. The unique stackable design makes it space-saving. You can stack 4 stools together in one corner to save space when not in use. It is also the perfect choice for your home life, being used as a kitchen, breakfast or bar stool with a super comfortable sitting experience of its perfect height. Colour: Black
